PEGGINGjWIACHINE.

SPECIFICATION forming part of Letters Patent N o. 707,498, datedAugust 19, 1902.

Application iiled March 16,1901. Serial No. 51,552. (No model.)

Be it known that I, JOHN E. BICKFORD, of Whitman, in the county of Plymouth and State of Massachusetts, have invented a new and useful Improvement in Begging-Machines, of which the following, taken in connection with the accompanying drawings, is a specification. Y

My invention relates to a peculiar arrangement of parts and to the construction of the same in a pegging-machine; and it consists in an adjustable feed mechanism and in minor mechanical details, which may be best understood by reference to the full description.

The object is to simplify the general construction and to make an improved adjustable feed. These objects I attain by the mechanism shown in the accompanying drawings, in which- Figure l shows in elevation all of my machine except the lower part of the horn and the supporting-post. Fig. 2 is a side elevation of the same. Figs. 3,4, and l5 illustrate in detail an adjustable gage or cam-block for governing the motion of the feed-plate. Fig. 6 is a vertical section showing the ring-feed and its connected parts.v

In the drawings the supporting-post of the nachine is indicated by A, and the horn by il. The head and head-plate of the machine are indicated by A A5. The head is attached to the supporting-post by screw-bolts A2. The main shaft oi' the machine is not shown on the drawings except that its end is shown at B, Fig. l. This main shaft is journaled in a suitable bearing in the head of the machine. The shaft is driven by the loose pulley B', which has a clutch connection B2 B2l with the main shaft. The large cam-wheel C is also normally loose on the main shaft, but may be connected with it and the driving pulley by the clutch device B3 B1. The entire clutch device, including the lever B5 and its connection, is known as the Varney clutch and need not be more fully described, asit is well known and in common use.

The feed-plate F is connected to the headplate A5 by a dovetail slide, (indicated at A,

Fig. 2,) so as to have a limited lateral motionthat is, a feeding motion-sufficient to cause the awl and driver to move laterally back and forth a distance equal to the desired pegspace, as will be explained. The feed-plate F has attached to it an awl-carrying plate E, which slides -vertically in said feed-plate and is operated by a crank-block D, Fig. 1, attached to a crank-pin D2 on the disk D', which in turn is connected to the main shaft B. The lateral or feed motion is given to both the awl and feed-plates by a device whicl I will now describe.

An arm Eis attached to the awl-plate E by screws or other suitable means and has a roller E2 extending back from it. (See dotted lines in Fig. 2.) This roller engages with a cam-slot G G', made in the cam-slot block F F2. The cam-slot block is made in two parts, as shown in Figs. 3 and 4. The upper part F is rigidly attached to the head-plate Ar of the machine by screws S, one of which is shown in Fig. 2, the screws passing through the holes S S in the part F', (see Fig. 3;) but the lower part F2 of the cam-slot block is ad justably attached to the said head-plate by means of screws S2, one of which is shown in Fig. 2. These screws pass through elongated holes S3 S3, made in said part, (see Fig. 5,) so that the lower part F2 of said cam-block can be adjusted laterally in relation to the upper part F'. Looking at Fig. lit may be readily understood that as the awl-plate E moves up and down the cain-roller E2 on the arm E will work in the slot G G, and as that slot is not a straight vertical slot it is evident that the said awl-plate E must have a lateral motion, and as the said plate E has no lateral motion in the feed-plate F the said feed-plate F must also have a lateral motion, the extent of which will be governed by the slot G G. To regulate this feed motion, the lower part F2 ofthe cam-slot block may be adjusted laterally by slacking the screws S2, moving the part to the desired position, and then tightening the said screws.

Motion is given to the drive-bar C10 by the following-described device: The drive-bar()10 is adj ustably attached by screw-nuts C2 C8 to the yoke-piece C7, which is connected to the arm C4 of the rockenshaft C3 by means of a block C in the slot C5. (See Fig. l.) Motion is given to the rocker-shaft C3 by means of an arm C2, which has a cam-roller C at its lower end, which engages with a camfgroove c c c c in the cam C. The cam-groove is ar- IOO ranged to cause the driver-bar O10 to ascend during the passage of the groove (in contact with camrroller U) from c3 to c, then to remain up and without motion from cto c2, and

yto descend with great velocity during the sists of a ring FG, Fig. l, (shown in detail in Fig. 6,) which is held securely to thefeedplate F and is free to rotate in the direction of the arrow, Fig. 6, but is held from rotation in the other direction by spring-pawls P P. These pawls P P are set differentially in relation to the teeth of the ratchet on the feedring. So if one of the pawls does not engage with the ratchet some other one will. Thus the feed-wheel will be held in any position that it may stop in. The action of the ringfeed may be explained as follows: We will suppose that the sole ofthe lshoe is pressed against the under surface of the feed-ring (in which case the feed-ring becomes or acts like 'a feed-foot) and that the feed-plate F and feed-ring occupy the right-hand position. Now as the machine Works the feed-plate will bevforced to the left. This action will cause the feed-ring to move to the left, and (as the feed-ring cannot turn, being held by one of the pawls P P) thus move the shoe one pegspace to the left, the shoe sliding on the horn H. As the feed-plate moves back to its original position the ring-feed is free to roll on the sole of the shoe, so as to assume its righthand position, ready for the next feed movement.

scribed, as they are old and Wellknown in A the art.

In the above description I have included the peg-driving mechanism, but do not claim any part of the peg-driving mechanism in this application, as that will be the subject-matter of a division of this case.

I claim- In a pegging-machine a peg-driver, a feedplate mounted for lateral movement in the machine-head, feed devices carried by said feed-plate, an awl-plate mounted for vertical movement in said feed-plate, an awl carried by said awl-plate, means to vertically reciprocate said awl-plate, a laterally-projecting arm on said awl-plate, a cam-roll carried by said arm, a plate attached to the machinehead and provided with an adjustable camgroove, whereby, as said pawl-plate is vertically reciprocated, it and the feed-plate will be given a simultaneous lateral movement to feed the Work, the extent of said feed movement being dependent upon the adjustment of the cam-groove, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specication, in the presence of two subscribing Witnesses, on this 15th day of March, A. D. 1901.

It is hereby certified that in Letters Patent No. 707,498, granted August 19, 1902, upon the application of John E. Bickford, of Whitman, Massachusetts, for an improvement in Pegging-Machines, an error appears in the printed specification requiring correction, as follows: In line 60, page 2, the Word paWl-plate 7 should read azul-plate;

and that the said Letters Patent should be read with this correction therein that the same may conform to the record of the ease in the Patent Oice.

Signed and sealed this 9th day of December, A. D., 1902.
